Description

  The present invention relates to an aqueous suspension of crosslinked silicone particles, an aqueous emulsion of oil containing crosslinked silicone particles, and a cosmetic raw material. More specifically, the present invention relates to an aqueous suspension of crosslinked silicone particles having excellent stability and less impact on the environment and the human body, an aqueous emulsion of oil containing crosslinked silicone particles, and a cosmetic raw material.

  Aqueous suspensions of crosslinked silicone particles comprising crosslinked silicone particles, a surfactant and water, and aqueous emulsions of oils containing crosslinked silicone particles are known (JP-A 63-309565, JP-A 11-140191). Gazette, JP 2000-281903). When such a suspension is added to a water-based paint, it has been proposed that the coating film exhibits matting properties (see Japanese Patent Application Laid-Open No. 5-9409), and that when used in a water-based cosmetic, the feeling of use is improved ( (See JP-A-10-139624 and JP-A-10-175816).

  In these aqueous suspensions and aqueous emulsions, a surfactant comprising a nonionic surfactant, an anionic surfactant, a cationic surfactant, an amphoteric surfactant or a mixture thereof is used. In particular, when used for cosmetic applications, nonionic surfactants such as alkyl polyethers are preferably used because the dispersibility of the crosslinked silicone particles and the oil containing the crosslinked silicone particles is good. .

  In recent years, in these water-based suspensions and water-based emulsions, there has been a demand for the selection of a surfactant with a low environmental load while improving the stability of the water-based suspension and the water-based emulsion. For example, alkyl polyethers having an alkyl group with 12 to 15 carbon atoms are certified as designated chemical substances that require the release of PRTR (Pollutant Release and Transfer Register) as chemical substances that are likely to have an impact on the environment. , Its use is becoming limited. In addition, surfactants derived from tallow such as beef tallow, especially surfactants having an alkyl group derived from tallow, are the quality and safety of pharmaceuticals manufactured using products derived from cattle etc. The use of cosmetics and the like is being restricted by the notification of “Ensuring Sexuality (December 12, 2000)”.

As a result of intensive studies to solve the above problems, the present inventors have found that as a surfactant used in an aqueous suspension of crosslinked silicone particles or an aqueous emulsion of oil containing crosslinked silicone particles, a specific N-acyl - N- The inventors have found that the above problems can be solved by selecting a hydrocarbon taurine and / or a salt thereof, and have reached the present invention.

  That is, an object of the present invention is to provide an aqueous suspension of crosslinked silicone particles and an aqueous emulsion of oil containing the crosslinked silicone particles that are excellent in stability and have little impact on the environment and the human body, and these aqueous suspensions and aqueous emulsions. It is to provide the used cosmetic raw materials.
